Embodiment Construction

[0051] A control device for a linear compressor according to a preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0052] Such as figure 2 As shown, in the linear compressor, an inflow pipe 2a and an outflow pipe 2b for sucking and discharging refrigerant are installed at one side of the sealed container 2, the cylinder 4 is fixedly installed in the sealed container 2, and the piston 6 is installed in the cylinder. The barrel 4 linearly reciprocates for compressing the refrigerant sucked into the compression space P in the cylinder barrel 4 , and various springs elastically support the piston 6 in the moving direction of the piston 6 . The piston 6 is connected to a linear motor 10 for generating linear reciprocating driving force.

[0053] At one end of the piston 6 that is in contact with the compression space P, a suction valve 22 is installed. At one end of the cylinder 4 that is in contact with th...

Abstract

The present invention discloses a control apparatus for a linear compressor which can vary a cooling force and prevent an inrush current. The control apparatus for the linear compressor includes a coil winding body (L) laminated on the linear compressor, a first capacitor (C1) connected in series to the coil winding body, a capacitance varying unit (50) being formed in a parallel structure to thefirst capacitor (C1), and having a capacitor switch (SW2), and a control unit (60) for inducing an output change of the linear compressor, by varying the whole capacitance of the control apparatus bycontrolling the capacitor switch (SW2).

Description

technical field [0001] The present invention relates to a linear compressor, and more particularly, to a control device for a linear compressor capable of varying cooling force and preventing surge flow. Background technique [0002] In general, a compressor is a mechanical device used to increase pressure by receiving power from a power generating device such as an electric motor or a turbine and compressing air, coolant, or other various working gases. Compressors are already widely used in household appliances such as refrigerators and air conditioners, or throughout industry. [0003] Compressors are roughly classified into reciprocating compressors, rotary compressors, and scroll compressors. In the reciprocating compressor, a compression space for sucking or discharging working gas is formed between a piston and a cylinder, and the piston linearly reciprocates inside the cylinder to compress a coolant. In the rotary compressor, a compression space for sucking or disc...
